STEAM WATE R-TAN K.

Speoillcationforming part of Letters Patent No. 21,694, dated'Octobcr 5, 1858.

scribed, by which water is elevated and ref tained, as herein more fully set forth.

Figure l is a perspective View. Fig. 2 is a horizont-al section. Figs. 3 and A are vertical sections.

The frame between which We set our tank is composed of four pieces of timber, J J J J, with notches to receive tank A and sustain it between them. Two of the timbers J J exy tend above tank A on opposite sides, so that cross-bar I passes over the center of the diameter of top W. rIemper-screw Z passes through cross-bar I and plate S, so as to op# erate upon top XV, to which is attached, on the under side, a gum-elastic gasket, X, so as to make an air-tight joint between .top W and sides of tank A.

B is a pipe communicating with any well. The top of said pipe B is intended to be above the surface of the water in tank A, so that when a partial vacuum is formed in tank A Water may ascend into tank A, but cannot pass Vout when the vacuum ceases to draw. Gage U is fastened to pipe B, so as to allow valve C to rise a sufficient height to permit water to pass from pipe B into tank A through two holes on opposite sides of valve C, as shown at Fig. 3, the upper end of valve C being closed by a gum-elastic gasket, X X, and held iirmly by metal plate I I on top. The gum-elastic gasket on top of valve (l is intended to close the upper end ot' pipe B and make it air-tight at all times, except when the vacuum draws it up against gage U, and the water flows into tank A until the vacuum is lled. A vacuum is produced in tank A by steam from any locomotive-boiler on railroad l? by turning pipe D over the safetyvalve of any locomotive. Steam may be forced into tank A through stopcock G2, which will immediately drive out the air at stop-cock M. Upon theplexus O O, attached to stop-cock Grl and stop-cock M, also rests pipe D, which is made flexible by a gum-elastic connection, E, between pipe D and stopcock G`.

Q, R, and V are braces attached to collar Y.

F is a stop-cock or valve of any kind by which water may be drawn from tank A while steam is being introduced. H H isan airpi pe extending from valveF inside and reaching near top W of tank A, to permit air to pass up, so that the water. may flow freely out whenever valve Fis opened. -Vhen steam is introduced, it will aii'ord sufficient pressure on the surface of the water in tank A; but in the absence of steam the air-pipe will be necessary, and is made for that contingency.

To operate steam-tank A, as described, apply the hand to crank N, attached to plexus O O, turn toward railroad P, and when at right angles therewith introduce steam through pipe D, which will expel the air from tank A through stop-cock M. As soon as the air is driven out sufficiently, turn pipe D again parallel with railroad P by crank N, and plexus O O closes the stop-cocks air-tight, when the steam immediately condenses and the vacuum forms and thewater rises in pipe B and flows into the tank A through holes in valve C. K

Vha-t We claim as our invention, and desire to secure by Letters Patent, is

l. The extension of pipe B above. the bottom and inside of tank A, in combination with valve C and gage U, or their equivalents, in the manner and for the purposes herein set forth.

2. The flexible pipe D and stopcocks CT2 and M, in combination with plexus O O and airtight tank A, as herein set forth.
